Abstract
A system for increasing electrical power includes an exhaust gas turbine, a generator, and a controller. The exhaust gas turbine is configured to be driven by exhaust gas from an engine. The generator is coupled to the exhaust gas turbine to produce electrical power for an electrical load. The controller is configured to increase the electrical power produced by the generator in response to a certain decrease in an electrical load voltage of the electrical load when the engine is at idle. The controller increases the electrical power by increasing a throughput of the exhaust gas through the exhaust gas turbine.
